The purpose of this study is to investigate how Finnish pre-adolescents perceive religion and spirituality. The participants of the study are 12- to 13-year-old Grade 6 pupils (N=102). The pupils were asked to give their meanings of religion and spirituality. The data includes over 700 written expressions on the two concepts. The qualitative content analysis of the data produced three dimensions. They were called the institutional dimension, the humanistic dimension, and the supernatural dimension. The students emphasized different dimensions in the data concerning religion compared to the data concerning spirituality. Most of the meanings given to religion belonged to the institutional dimension (68.2%). In the data concerning spirituality most of the meanings belonged to the humanistic dimension (66.2%).
